Trivia: My Little Pony: Friendship Is Magic S2 E20 "It's About Time"
Recycled Script: The episode begins with Twilight discovering an upcoming crisis and she begins looking for ways to avert it. Her sanity and physical appearance degrade as her efforts fail to pan out, resulting in her using magic to fix the problem, only to find out she was overreacting and the problem she was afraid of wasn't such a big deal after all. This episode's premise is very similar to Lesson Zero.
Jossed: The theory that Doctor Whooves would play an important role in this episode. He does appear, but only as a background character when Twilight is telling everypony about what will happen. Twilight's Time Travel turned out to be from one of her spells.
